The present invention provides that the lamp has a conventional beautiful outlook and has a greater heat dissipation area so that the temperature of the lamp is reduced greatly. Furthermore, the cost is down and less material is used. further the lifetime of the LED lamp is prolonged.
BACKGROUND OF THE INVENTIONLED has widely used in many field due to small volume and power saving. However currently, LEDs have the problem of heat dissipation. This make the high power LED can not replace the convention illumination device effectively. The heat dissipation will increase with the increment of the temperature of the LED, while this will short the lifetime of the LED.
